Broadcom Bluetooth Chips
|
|
---------------------
|
|
|
|
This documents the binding structure and common properties for serial
|
|
attached Broadcom devices.
|
|
|
|
Serial attached Broadcom devices shall be a child node of the host UART
|
|
device the slave device is attached to.
|
|
|
|
Required properties:
|
|
|
|
- compatible: should contain one of the following:
|
|
* "brcm,bcm43438-bt"
|
|
|
|
Optional properties:
|
|
|
|
- max-speed: see Documentation/devicetree/bindings/serial/slave-device.txt
|
|
- shutdown-gpios: GPIO specifier, used to enable the BT module
|
|
- device-wakeup-gpios: GPIO specifier, used to wakeup the controller
|
|
- host-wakeup-gpios: GPIO specifier, used to wakeup the host processor
|
|
- clocks: clock specifier if external clock provided to the controller
|
|
- clock-names: should be "extclk"
|
|
|
|
|
|
Example:
|
|
|
|
&uart2 {
|
|
pinctrl-names = "default";
|
|
pinctrl-0 = <&uart2_pins>;
|
|
|
|
bluetooth {
|
|
compatible = "brcm,bcm43438-bt";
|
|
max-speed = <921600>;
|
|
};
|
|
};
